Abstract

An internal combustion engine (1), in particular, for a motor vehicle, is disclosed, comprising a catalyst (12), which can be treated with nitrogen oxides. A lambda probe (13) is provided, for the measurement of oxygen concentration after the catalyst (12). The nitrogen oxides which are fed to the catalyst (12) may be increased by a controller (18) and, by means of an increase in the oxygen content after the catalyst (12), the conversion efficiency of the catalyst (12) may be determined.
